Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for producing worm-based sweetfish granule fertilizer, in which worms are cultured in sludge generated from industrial wastewater treatment or sewage treatment, and the true worms are collected and dried. The purpose of this method is to produce fertilizer rich in organic substances through the discarded sludge, thereby simultaneously achieving waste disposal and effective utilization.

The sludge used in the present invention is generated from industrial wastewater treatment such as beer manufacturing and processed seafood food manufacturing, or from general sewage and human waste treatment, and has a high content of organic matter that can be used as feed for worms, and contains arsenic. .

It is desirable that it does not contain harmful substances such as cadmium.

Furthermore, lime-treated sludge cannot be used because worms do not grow there.

The embodiment shown in #i will be described below. The sludge is dehydrated and adjusted to a hardness that allows it to be deposited in a certain shape, and then placed at a place Qi where Wr is required indoors or outdoors, with a width of 1 to L 5 m s and a length of 20 m s. It is deposited in a semicylindrical shape with a height of ~25 m1 and a height of 30 to 50 cm.0 A large number of worms (not shown) are found on the above deposited sludge.
Cover it with sheet 2 to protect it from sunlight and protect it from external enemies (Figure 1).

The above worms breed by feeding on sludge 1, excrete fecal particles (not shown) on the surface, and produce 10 to 15 cfn in 10 to 15 days.
The sludge layer l& with a thickness of 1 ↓ is eclipsed, and the excreted feces particles are deposited in this area (Fig. Hatake 2).

When the fecal particles have accumulated to an appropriate thickness, remove the sheet 2 and leave it for 1 to 2 days, and the worms will migrate into the sludge layer lb below the accumulated n particles, so collect the accumulated fecal particles. (Fig. 2) 0 Afterwards, when the sludge 1 is layered again with the sheet 2, the worms move to the upper part of the sludge layer 1b, breed, and discharge 8 grains on the surface, so 10 to 15
After a day has passed, 8 grains are collected in the same manner as in the case of the sludge layer 1a.

Next, worms multiply in the sludge layer 1c below the sludge@xb and 18 worms are discharged in the same manner as in the above case, so that after θ "the required number of days, approximately 10 cI from the bottom of this sludge layer 1c
Eight grains are collected in the manner described above, leaving a sludge layer 1e' with a thickness of about n.

The above sludge contains worms, worm follicles, and larvae that have bred, so leave it as it is and pile up new sludge on top of it (Fig. 3). If you mix it with a sheet, the worms will Kh particles move from the sludge layer 1c' to the surface layer of the new sludge 1' and multiply, and the surface Kh particles are discharged, so they are collected in the same manner as in the above case.

The 8 grains thus collected are dried in the sun or with a hot air blower, and passed through a sieve to remove pebbles, dirt, etc. to obtain 8 grains of Shimizu fertilizer. The figure shows another embodiment, which is the same as the previous embodiment except for the process of adding new sludge after eight grains have been collected.

That is, the sludge 3 is piled up in a plurality of rows in the same shape as the sludge 1, and as shown in FIG.
The worms are arranged in parallel with a space 4 for the row, and worms are propagated in the same areas as in the case of the sludge 1, and 8 worms are collected.

Then, when finally collecting 8 grains, leave a sludge layer 3' with a thickness of about 10 cIn as in the previous embodiment, and deposit new sludge 5 in each space 4 in the same kamabot shape. When the sludge 5 and the sludge 43' are kept in contact with each other (FIG. 5), the worms of the sludge layer 3' migrate to the adjacent sludge 5 over a period of 3 to 5 days.

Thus, after the worms have migrated, a sludge layer 3' consisting of almost 8 grains is collected, and in the space where this sludge layer 3' has been collected, when the collection of 8 grains from the sludge 5 is finished, In step 1, new sludge is deposited in the same manner as above, and the same operation is repeated successively.

Although the 8-grain fertilizer produced in both of the above examples differs somewhat from the component pressure of sludge, analysis shows that the moisture content is 51.
89%, nitrogen 3.08%, phosphorus 3.70%, potassium 0.
35%, organic matter 22.35%, and pH 6.60, and it was found that the trial fertilizer effect was good.

In addition, the worms cultured in conjunction with the production of the fecal fertilizer can be appropriately collected and used as feed for fish farming.

As is clear from the above description, according to the present invention,
Since worms are cultivated using sludge as bait, and the excreted feces particles are used as fertilizer, it does not require special power-free mechanical equipment, and it is possible to simultaneously manufacture fertilizer and dispose of sludge. Cultured worms LA can be used as fish feed, etc., making it extremely productive and economical.
